# Course Introduction

> This article introduces a hands-on Kubernetes Networking course featuring browser-based labs and covers essential networking concepts and tools.

Welcome to the **Kubernetes Networking** course! I’m Weston Bassler, your instructor for this hands-on journey into container networking. Unlike traditional tutorials, this course features instant, browser-based labs so you can apply new concepts the moment you learn them.

  All labs spin up directly in your browser—no local installation needed. Just log in and start practicing!

## Browser-Based Hands-On Labs

We believe in learning by doing. After each lesson, you’ll work through real-world scenarios that reinforce key concepts and tools.

## What You’ll Learn

By the end of this course, you’ll have a thorough understanding of Kubernetes networking—from basic pod connectivity to advanced security policies and multi-cluster topologies.

| Module                                 | Topics Covered                                                                                                         |
| -------------------------------------- | ---------------------------------------------------------------------------------------------------------------------- |
| 1. Kubernetes Networking Architecture  | Host-only vs. Pod-to-Pod communication, Overlay networks, CoreDNS, Network Policies                                    |
| 2. Container Network Interfaces (CNIs) | Installing and configuring Calico, Flannel, Weave; deep dive into Cilium features and eBPF                             |
| 3. Kubernetes Services                 | ClusterIP, NodePort, LoadBalancer, ExternalName; Endpoints & EndpointSlices; DNS-based service discovery               |
| 4. Ingress Controllers & Resources     | Deploying Traefik Ingress; ExternalDNS integration; Intro to Service Mesh and multi-cluster routing                    |
| 5. Network Security                    | mTLS encryption & authentication; cert-manager with Let’s Encrypt; Cilium Network Policies; Hubble CLI troubleshooting |

## Why This Course Stands Out

1. Instant browser labs—no VM setup or cluster installation required.
2. Real-world challenges—solve common networking issues yourself.
3. Deep dives into Cilium and eBPF—stay ahead with cutting-edge CNI technology.
4. Community support—join the discussion on the [KodeKloud Forum](https://kodekloud.com/forum).
